In raid finder there must be a certain amount of tanks, heals, and dps or it simply will not pop.
Why can’t something like this be done for mini games (eso does this).
Each team has 1 tank, 1 healer, 4 dps. The mini pops and you have balance. It isn’t a perfect solution of course but it would be an incredible start to establish some balance.
I think it should be a separate mode though due to low population of the game.
